- Advantages and disadvantages of gate valvesGate valve is a widely used valve. Generally, cut-off devices with a diameter of ≥50mm are selected for use, and sometimes gate valves are also used for cut-off devices with a small diameter.一, Advantages of Gate Valve:1. Low fluid resistance2. Less external force required for opening and closing3.
- Features of Gate ValveLight weightThe body is made of high-grade nodular cast iron, the weight is about 20%~30% lighter than the traditional gate valve, and the installation and maintenance are convenient.Flat bottom brake seatTraditional gate valves often silt in the bottom groove of the valve due to foreign objects suc
- Steps to choose valve1. Clarify the purpose of the valve in the equipment or device, determine the valve's working conditions, applicable medium, working pressure, working temperature, etc. 2. Clarify the nominal diameter and connection method of the pipeline connected to the valve: flange, thread, welding, etc. 3
- How to clean and assemble the valveCleaning Steps: The valve parts must go through the following processes before assembly: 1.
